A wide range of expansion modules allows to set up an individual LOGO! configuration.
LOGO! 8: 24 digital inputs, 20 digital outputs, 8 analog inputs and 8 analog outputs!

If you do networking of several LOGO! one configuration can be expanded to overall 88 digital inputs, 80 digital outputs, 40 analog inputs and 24 analog outputs.
LOGO! 8 can also be connected to KNX sytems.

To combine different voltage levels you have to keep the following rule:
The basic module must be a 230 V version followed by 230 V expansion modules. Then an analog module must be used to achieve a galvanic isolation. Right from the analog module further analog modules or 12V / 24 V expansions can be attached.
